Romans 4:4-8

4 Now to him who works, the reward is not counted as grace, but as debt.  5 But to him who doesn't work, but believes in him who justifies the ungodly, his faith is accounted for righteousness.  6 Even as David also pronounces blessing on the man to whom God counts righteousness apart from works,

7 "Blessed are they whose iniquities are forgiven,  Whose sins are covered.

8 Blessed is the man whom the Lord will by no means charge with sin."
